From the foregoing description, it will be appreciated that a cabinet has been provided having a source of moisture at its lower part and having its drawers so arranged and so mounted within the cabinet, that space either at one or both sides of the drawers or at the rear end of the drawers serves as a vertical flue or flues through which the moisture may rise. It will further be noted that the drawers are spaced from one another so that the moisture rising through the vertical flue or flues, may spread horizontally over the contents of the drawers.

What I claim is:

A cabinet having openings in its front, a series of drawers normally closing said openings, said drawers being supported in spaced relation, one above another on the side walls of the cabinet and in spaced relation to the inner surfaces of said walls, and a tray in the lowermost drawer of the series, said tray having a series of partions at right angles to the line of movement of said tray when it is withdrawn, said tray also having a rim connected to the upper part of its sides and inclined towards the tray bottom.
